Electrochemical performance of lanthanum cerium ferrite nanoparticles for supercapacitor applications

Lanthanum cerium ferrite nanoparticles has been synthesized for the first time via hydrothermal and co-precipitation method. The structural morphological study of have examined using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM) energy dispersive spectroscopy (EDX). electrochemical J1 J2 electrodes three electrode system in 6 M KOH electrolyte cyclic voltammetry (CV), galvanostatic charging-discharging (GCD) impendence (EIS). highest specific capacitance 1195 F/g obtained at a scan rate 10 mV/s from synthesis nanomaterial (J2) long cycling life 92.3% retention after 2000th cycles. Furthermore, density power current 5 A/g was 59 Wh/kg 9234 W/kg, respectively. Hence, fabricated is favorable candidate super-capacitor applications.
